Open a new upload session for an existing dataset
Get a fresh presigned URL to upload a new version into a dataset you already have — a
corrected file, or the next chunk of history. Behaves the same way POST /datasets does
for a brand-new dataset's own upload: at most one upload session is open per dataset at a
time, so calling this again before finalizing just hands back that same session rather
than opening a second one — safe to call repeatedly if a response gets lost.
Once a session has been finalized (successfully or not), the next call here opens a
genuinely new one for that dataset's next version.
